GRT319 OLT mai nisa don HFC zuwa FTTH

GRT319 Nesa OLT an ƙera shi don maye gurbin kumburin gani na HFC, yana canza hanyar sadarwar rarraba coaxial na mita 100 na ƙarshe zuwa fiber na mita 100 na ƙarshe zuwa cibiyar sadarwar gida, yana ba da sabis na intanet na DVB-C RF da GPON ga duk masu biyan kuɗi na CATV. Tare da gidaje masu hana ruwa na Aluminum, GRT319 yana da tashar shigar da fiber guda ɗaya inda bayanan 10Gbps da 1550nm CATV RF suke kai tsaye daga Headend ta WDM, adana hannun jarin fiber na gangar jikin. GRT319 yana da fitarwar fiber guda ɗaya wanda ke haɗa ginanniyar 20dBm EDFA da tashar GPON OLT guda ɗaya, tana tallafawa masu biyan kuɗi har zuwa 256 a cikin radius na kebul na FTTH na mita 100. Yin aiki tare da GFH1000 FTTH mai karɓar CATV, GRT319 Remote OLT yana riƙe DVB-C STB kasuwanci kawai don masu biyan kuɗi na CATV. Yin aiki tare da GONU1100W FTTH ONU, GRT319 Remote OLT yana ba da intanet na 2.5Gbps ban da CATV RF.

Node by node, GRT319 na iya taimakawa CATV MSO mai juyar da tsarin HFC CATV hanya ɗaya zuwa tsarin FTTH mai matakai biyu mataki-mataki a kasafin kuɗi mai araha.

Akwai miliyoyin DVB-C STBs suna aiki a tsarin CATV na yanzu. Za mu kiyaye su yayin gabatar da ƙarin ayyukan intanet. OLT mai nisa ya fi kyau lokacin HFC zuwa FTTH. 

Muna kiyaye hanyar sadarwar tauraro 1550nm zuwa kowane kumburin gani kuma muna gabatar da 10Gbps akan fiber iri ɗaya zuwa kumburin gani ta WDM.

Ana maye gurbin tsohuwar kumburin gani da ɗaya Remote-OLT a wuri ɗaya da wutar lantarki iri ɗaya.

Tsoffin masu raba coaxial da igiyoyi ana maye gurbinsu da masu raba PLC da igiyoyin FTTH don rufe duk masu biyan kuɗi.

OLT mai nisa yana goyan bayan shigarwar fiber 1 da fitarwar fiber 1.

Fiber ɗin da ake fitarwa yana da siginar 20dBm 1550nm da GPON OLT ɗaya don matsakaicin masu biyan kuɗi 256. 

A kowane ɗakin FTTH, akwai tashar tashar TV kawai ko zaɓin tashar tashar TV + Intanet.
